Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of retirement home operator Brookdale Senior Living (NYSE: BKD) posted a mercurial 10.5% gain today amid heavy trading.

So what: The company reported earnings this morning -- and missed analyst targets on both the top and bottom lines. However, management signaled a willingness to go on a buying spree as the industry consolidates, and even expanded its line of credit by $30 million.

Now what: In case you're skeptical, Brookdale intends to use the larger credit line to "pursue opportunities as they arise," and you can't get much clearer about acquisitive intentions than that. In a combined cash-and-stock deal, I can see Brookdale making a play for tightly run operations such as Capital Senior Living or Emeritus in the next year or so.
